SUPPORT FOR FLOOR CONSTRUCTION.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed January 31, 1905. Serial No. 243,496.

of the King of Italy, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Support for Floor Construction, of which the following is a full, clear, and exact description.

The invention relates to fireproof floor construction; and its object is to provide a new and improved support for sustaining the filling between the beams while placing the filling in position, the support being very simple and durable in construction, easily set up, and readily taken down after the filling is in p ace.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an end elevation of the improvement in position on adjacent I floor-beams. Fig. 2 is a side elevation of the same. Fig. 3 is a like view of the same, showing the crossbars lowered for the convenient removal of the planks; and Fig. 4 is an end elevation of the improvement as arranged for the construction of arched ceilings.

The planks A for supporting the fillingbricks or other filling B between the floorbeams 0 rest on two or more transverse bars D, preferably in the form of T-bars, each supported at its ends by hangers E and F, having angular offsets E and F for engaging opposite base-flanges of the I floor-beams C, as plainly shown in the drawings. The hangers E are preferably fixed to the bars D, while the other hangers F are slidably mounted on the bars D to allow spacing the hangers according to the distance between the adjacent I-beams. Each hanger F is provided on its under side with a member F preferably made L shape and pivoted at F to the hanger, so that when the member F is in a normal position, as shown in Figs. 1 and 2, its free end is engaged by a link G, having a handle and fulerumed on a hook-like projection F", forming part of the hanger F. Thus when the link G engages the member F the bar D is firmly supported in the hanger F.

In using the device the hangers E and F are hung onto the floor-beams C and the planks A are placed in position on top of two or more of the cross-bars D. The bricks B or other filling can now be readily placed in position between the I-loeams (J, it being understood that the said bricks rest on the planks A until the filling between the I-beams is completed. When this has been done and it is desired to remove the device from the floor construction, it is only necessary for the operator to disengage the link G from the free end of the member F to allow the latter to swing downward, thus releasing the end of the bar D at the hanger F. The'bar D is now allowed to swing downward at this end a suitable distance, (see Fig. 3,) and then the bar is held in position by the use of a rope H or similar device hung on the hook-like projection F When the several bars D have been lowered at one end in the manner described, it is evident that the several planks A can be readily pulled out, and when this has been done the ropes H are disengaged from the bars D to allow the operator to readily unhook the hangers E and F from the floor-beams C.

It is understood that the hangers E and F are very thin in their upper portions, so that they take up little room on the floor-beams, and the filling-bricks B at the floor-beams are cut out sufiicientlyto allow placing the end bricks in position.

For the formation of flat ceilings the bars D are straight, as shown in Figs. 1, 2, and 3, and in case an arched ceiling is to be formed the bars D are curved correspondingly, as will be readily understood by reference to Fig. A.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent 1. A support for floor construction comprising a bar, hangers on the ends of the bar for engaging the floor-beams, one of the hangers being adapted to be opened to drop this end of the bar, and a flexible support on the open hanger, for engaging and supporting the dropped end of the bar.

2. A support for floor construction, comprising a bar, a hanger fixed on one end of the bar, a hanger slidable on the other end of the bar and provided with a hinged member adapted to swing downward to release the bar, and a link pivoted on the slidable hanger and adapted to engage the free end of the said hinged member, to hold the latter in a closed position.

3. A support for floor construction, comprising a bar, a hanger fixed on one end of the bar, a hanger slidable on the other end of the bar and provided with a hinged member adapted to swing downward to release the bar, the said slidable hanger having a hook, and a flexible support hung on the said hook and adapted to engage the said bar.

In testimony whereof I have signed my name to this specification in the presence of two subscrlbing wltnesses.

LUIGI VIEZZI.
